Description

Technical Field

[0001] This application belongs to the field of fitness equipment technology, and in particular relates to a standing leg-clamping training device. Background Technology

[0002] In recent years, with the popularization of fitness awareness, the number of people exercising has continued to rise, which in turn has led to a continuous increase in the demand for fitness equipment.

[0003] The existing leg-clamping trainer includes a base frame, a seat cushion, a backrest cushion, two swing frames, and a resistance source. The seat cushion and backrest cushion are fixed on the base frame, and the two swing frames are rotatably mounted on the base frame and connected to the resistance source. The user sits on the seat cushion with their back against the backrest cushion and uses their legs to drive the two swing frames to perform leg-clamping exercises to strengthen their leg muscles.

[0004] However, when users sit on the cushion and lean back to perform leg-clamping exercises, they are prone to using their waist or other parts of their body for leverage, which can lead to poor training results and reduced training efficiency. Utility Model Content

[0005] To address the shortcomings of related technologies, this application provides a standing leg-clamping trainer. Through the cooperation of two swing frames, handrails, and foot pedals on the swing frames, the user can perform leg-clamping training by applying force to the swing frames with unsupported hips, avoiding the user's use of the waist or other parts of the body for leverage, thus improving training efficiency.

[0006] This application provides a standing leg-clamping training device, comprising:

[0007] Base frame assembly;

[0008] Handrails are provided on the base frame assembly and / or on the side of the base frame assembly;

[0009] A transmission assembly, which is connected to a resistance source;

[0010] The swing frame assembly includes two swing frames, both of which are rotatably mounted on the base frame assembly. At least one swing frame is connected to the transmission assembly.

[0020] An adjustment component, one end of which is connected to either of the swing frames and the other end of which is connected to the transmission component, is used by the user to adjust the limiting angle between the two swing frames.

[0021] In some embodiments, the adjustment component includes:

[0022] A wheel assembly, which is coaxially rotatably mounted on the first base frame with any of the swing frames, is connected to the transmission assembly, and has multiple locking points on the wheel assembly;

[0023] A pin is provided at one end on the swing frame and at the other end for inserting into or disengaging from the locking point to adjust the limiting angle, thereby locking or releasing the relative position of the two swing frames in both directions.

[0024] In some embodiments, the adjustment component includes:

[0025] A ratchet assembly, which is coaxially rotatably mounted on the first base frame with any of the swing frames, is connected to the transmission assembly, and has multiple slots on it;

[0026] A limiting member, one end of which is disposed on the swing frame, and the other end is used to cooperate with the slot to adjust the limiting angle, thereby locking or releasing the relative position of the two swing frames, and when the relative position is locked, it is a one-way lock or a two-way lock;

[0027] An elastic element is disposed on one side of the limiting element and abuts against the limiting element, the elastic element being used to provide force to push the limiting element into the slot.

[0028] In some embodiments, the adjustment component further includes:

[0029] A top plate component, which is rotatably mounted on the first base frame and located on one side of the ratchet component;

[0030] Connector, the connector being connected to the top plate member;

[0031] An adjusting member, one end of which is connected to the connecting member, and the other end of which extends along the length of the second upright until it is located on one side of the handrail frame. The adjusting member is used to drive the top plate to rotate relative to the first base frame through the connecting member, thereby providing force to push the limiting member out of the slot.

[0032] In some embodiments, the adjusting member is rotatably mounted on the base frame assembly at either end, and the end of the adjusting member near the handrail is used to pull the connecting member relative to the first base frame.

[0033] In some embodiments, the slot further includes a first slot and a second slot. The ratchet member is provided with at least one first slot and a plurality of second slots. The first slot is located on any side of the plurality of consecutively arranged second slots. The first slot is used to cooperate with the limiting member to lock the limiting angle in both directions. The plurality of consecutively arranged second slots are used to cooperate with the limiting member to lock the limiting angle in one direction.

[0034] In some embodiments, the top plate or the ratchet is provided with a limiting groove, and the ratchet or the top plate is provided with a corresponding limiting post. The limiting post extends into the limiting groove, and the limiting groove and the limiting post cooperate to limit the relative movement range of the top plate and the ratchet.

An adjustment component allows for quick adjustment of the limiting angle between the two swing arms, improving adjustment efficiency. The cooperation of a wheel and a pin allows for bidirectional limitation of the limiting angle, while the cooperation of a ratchet and a limiting member allows for unidirectional or bidirectional limitation of the limiting angle. An elastic element prevents the limiting member from rotating out of its slot, avoiding instability in the relative position of the two swing arms. The cooperation of a top plate, a connecting member, and an adjusting member allows for quick control of the limiting member's movement to another slot. The cooperation of a limiting post and a limiting groove limits the relative movement range of the top plate and the ratchet. The cooperation of a transmission component and a lever changes the direction of force, allowing the gravity of the resistance source to provide counterforce for the relative horizontal swinging of the user's legs. The cooperation of a first slot, a second slot, and a limiting member allows for flexible limitation of the limiting angle.

Figure 1 To be continued Figure 7 Specific embodiments are described below.

[0056] Reference Appendix Figure 1 and Figure 2 This application provides a standing leg-clamping training device, including a base frame assembly 100, a transmission assembly 200, a handrail frame 600, and a swing frame assembly 300. The handrail frame 600 is disposed on the base frame assembly 100, the transmission assembly 200 is connected to a resistance source, the swing frame assembly 300 includes two swing frames 301, both of which are rotatably disposed on the base frame assembly 100, and at least one swing frame 301 is connected to the transmission assembly 200. The swing frame assembly 300 also includes a foot pedal 302, which is disposed on the swing frame 301 and cooperates with the handrail frame 600 to support the user to stand and perform leg-clamping training.

[0057] Reference Appendix Figure 3 In some embodiments, the base frame assembly 100 includes a first base frame 101, a first upright frame 102, and a second upright frame 103. The first upright frame 102 is disposed at one end of the first base frame 101, the second upright frame 103 is disposed on the first base frame 101, and the handrail frame 600 is disposed on the second upright frame 103 away from the first base frame 101.

[0058] Specifically, the first base frame 101, the first upright frame 102, the handrail frame 600, the second upright frame 103, and the footboard 500 are made of high-strength steel or aluminum alloy to ensure their stability and load-bearing capacity during standing leg-clamping training. Using high-strength materials also improves the overall durability of the equipment, preventing deformation or damage after long-term use and ensuring training safety. The first base frame 101 can be a straight, curved, or multi-support structure to adapt to different ground conditions and increase stability.

[0059] The first upright 102 is located at one end of the first base frame 101. The first upright 102 is connected to the first base frame 101 by welding or bolting. The first upright 102 is used to support the resistance source so that the resistance source is at a certain height relative to the first base frame 101, thereby facilitating the user to drive the lever 202 to resist the resistance source for training.

[0060] The foot pedal 500 is located at the other end of the first base frame 101 relative to the first upright frame 102. The foot pedal 500 is used to provide a stable standing area on the first base frame 101 for the user before stepping on the swing frame assembly 300, making it convenient for the user to get on the machine, and to provide emergency avoidance when the user's legs are exhausted, ensuring the user's safety.

[0061] It should be noted that the size of the pedal 500 should be designed according to the user's foot size and standing posture habits to ensure a stable and comfortable standing position; optionally, the surface of the pedal 500 can be made with a non-slip texture or covered with a non-slip material to prevent the user from slipping during training.

[0062] One end of the second upright 103 is located on the first base frame 101 and between the first upright 102 and the pedal 500. The second upright 103 is connected to the first base frame 101 by welding or bolting. The second upright 103 is used to provide support for the lever 202 and the adjusting member 406. Optionally, the second upright 103 includes two parallel columns and a connecting beam. One end of the two columns is fixed on the first base frame 101, and the two ends of the connecting beam are respectively connected to the two columns to form a stable upright.

[0063] The handrail 600 is located at the end of the second upright 103 away from the first base frame 101. The handrail 600 is connected to the second upright 103 by welding or bolting. Optionally, the handrail 600 can be wrapped with a non-slip material, such as rubber or foam, to increase grip comfort and reduce the risk of hand injury. Optionally, the height and grip angle of the handrail 600 are adjustable to accommodate different user body shapes and training postures.

[0064] Reference Appendix Figures 1 to 3 In some embodiments, the transmission assembly 200 includes a transmission member 201 and a lever member 202. One end of the transmission member 201 is connected to the swing frame assembly 300 through the adjustment assembly 400. The two ends of the lever member 202 are respectively connected to the resistance source and the other end of the transmission member 201. The lever member 202 is rotatably mounted on the second stand 103 at any position between its two ends.

[0065] Specifically, the transmission component 201 consists of a long rod and connecting rod joints located at both ends of the long rod. The two connecting rod joints are threadedly connected to the long rod. The orientation of the connecting rod joint interfaces is set according to needs. The transmission component 201 is used to transmit power and change the direction of force.

[0066] The lever 202 includes a first arm, a second arm, and a rotating part. The lever 202 is rotatably mounted on the second stand 103 via the rotating part. The first arm is used to connect to the resistance source, the second arm is used to connect to the transmission component 201, and the rotating part is located between the first arm and the second arm. Optionally, the length from the second arm to the rotating part is less than the length from the first arm to the rotating part, so that the transmission component 201 needs more force to drive the lever 202 to drive the resistance source, thereby improving the exercise efficiency.

[0067] Reference Appendix Figure 3 In some embodiments, when the resistance source is a counterweight, the transmission member 201 needs to pull or push the lever member 202 to rotate relative to the second upright 103, thereby driving the resistance source to do work against gravity in the vertical direction. Therefore, the interface orientation of the linkage joint used to connect the lever member 202 is set to be along the horizontal direction. Furthermore, since the swing frame assembly 300 essentially drives the transmission member 201 to move in the horizontal direction through the adjustment assembly 400, the interface orientation of the linkage joint used to connect the adjustment assembly 400 is set to be along the direction of gravity or inclined to the direction of gravity, so that the swing of the swing frame assembly 300 in the horizontal direction is converted into a swing in the vertical direction through the transmission member 201, thereby driving the resistance source to do work against gravity in the vertical direction.

[0068] Reference Appendix Figure 1 and Figure 2 In some embodiments, two swing frames 301 are rotatably mounted on the first base frame 101. The standing leg clamping trainer also includes an adjustment component 400, which is connected to the swing frame assembly 300. One end of the adjustment component 400 is connected to either swing frame 301, and the other end is connected to the transmission assembly 200. The adjustment component 400 is used by the user to adjust the limiting angle between the two swing frames 301 in both directions or in one direction.

[0069] It should be noted that the limiting angle between the two pendulum frames 301 refers to the default angle maintained between the two pendulum frames 301 when not driven by user training, or the maximum angle between the two pendulum frames 301 when the user trains and drives the two pendulum frames 301 to swing relative to each other; the user can adjust the angle of the limiting angle by adjusting the component 400 before, after and during training.

[0070] Due to the different training needs or standing habits of different users, the limiting angles set between the two swing frames 301 are also different.

[0071] Reference Appendix Figures 3 to 5In some embodiments, the adjustment component 400 includes a ratchet component 401 and a limiting component 402. The ratchet component 401 is rotatably mounted on the first base frame 101 coaxially with any of the swing frames 301. The ratchet component 401 is connected to the transmission component 200. The ratchet component 401 is provided with a plurality of slots 4011. One end of the limiting component 402 is rotatably mounted on the two swing frames 301, and the other end is used to cooperate with the slots 4011 to adjust the limiting angle, thereby connecting or disconnecting the two swing frames 301 from the ratchet component 401, and locking or releasing the relative position of the two swing frames 301 in one direction.

[0072] Specifically, the ratchet component 401 is a circular, square, or other shaped metal plate component. The ratchet component 401 is coaxially rotatable on the first base frame 101 with any swing frame 301. One end of the ratchet component 401 is provided with a connector for connecting to the transmission component 201. The ratchet component 401 drives the transmission component 201 by rotating relative to the first base frame 101, thereby transmitting force to the transmission component 201. The ratchet component 401 is provided with multiple slots 4011. The depth and width of the slots 4011 are set to match the size of the limiting component 402 to ensure a stable connection.

[0073] The limiting member 402 includes a special-shaped plate and a pin head. The special-shaped plate is a plate-shaped component. One end of the special-shaped plate is rotatably mounted on the swing frame 301, and the other end is fixedly connected to the pin head. The outer diameter of the pin head matches the diameter of the slot 4011. The special-shaped plate rotates relative to the swing frame 301 to rotate the pin head into the slot 4011, thereby connecting the ratchet member 401 with the swing frame 301. Thus, when the user controls the swing frame 301 to swing, the ratchet member 401 and the transmission member 201 drive the lever member 202 to move.

[0074] It should be noted that the connection between the ratchet 401 and the transmission 201 is set according to actual needs. Optionally, the interface of the ratchet 401 is inclined to the rotation plane of the ratchet 401. Correspondingly, the interface of the transmission 201 is also inclined to the rotation plane of the ratchet 401. This is to ensure that the two ends of the transmission 201 can still transmit normally when they are at different heights relative to the first base frame 101. The shaped plate is used to abut against the elastic member 403. The specific shape of the shaped plate is set based on the purpose of making one end of the elastic member 403 abut against the shaped plate to limit the rotation of the pin head relative to the swing frame 301.

[0075] Reference Appendix Figure 3 In some embodiments, the adjustment assembly 400 further includes an elastic element 403, which is disposed on one side of the limiting element 402 and abuts against the limiting element 402. The elastic element 403 is used to provide force to push the limiting element 402 into the slot 4011.

[0076] Specifically, the elastic element 403 includes, but is not limited to, compression springs, tension springs, spring sheets, and rubber. The elastic element 403 is used to always press the pin head into the slot 4011 through the shaped plate to prevent the pin head from sliding out of the slot 4011 and to ensure the stable connection between the limiting element 402 and the ratchet element 401.

[0077] Optionally, the ratchet 401 is also provided with a stop post, and the elastic element 403 is sleeved on the rotating shaft of the profile plate. One end of the elastic element 403 abuts against the stop post, and the other end abuts against the profile plate, so that the profile plate always presses the pin head into the slot 4011.

[0078] Reference Appendix Figures 1 to 4 In some embodiments, the adjustment assembly 400 further includes a top plate 404, a connector 405, and an adjustment member 406. The top plate 404 is rotatably mounted on the first base frame 101 and located on one side of the ratchet member 401. The connector 405 is connected to the top plate 404. One end of the adjustment member 406 is connected to the connector 405, and the other end of the adjustment member 406 extends along the length of the second upright 103 until it is located on one side of the handrail frame 600. The adjustment member 406 is used to drive the top plate 404 to rotate relative to the first base frame 101 through the connector 405, thereby providing force to push the limiting member 402 out of the slot 4011.

[0079] Specifically, the top plate 404 is a circular, square, or other shaped metal plate component. When not pulled by the connecting member 405, the edge of the top plate 404 is tangent to the bottom wall of the ratchet 401 slot 4011. When the connecting member 405 drives the top plate 404 to move, the edge of the top plate 404 moves from the bottom wall of the slot 4011 towards the opening of the slot 4011, thereby causing the pin head located in the slot 4011 to resist the pressure of the elastic member 403 and be pushed out of the slot 4011. At this time, the connection between the ratchet 401 and the limiting member 402 is disconnected, and the included angle between the two swing arms 301 can be adjusted. After adjusting the included angle between the two swing frames 301 to a suitable position (i.e., the limiting angle), when the top plate 404 is driven to perform a reverse reset movement through the connecting piece 405, the edge of the top plate 404 moves from the opening of the slot 4011 towards the bottom wall of the slot 4011. The elastic piece 403 assists in pushing the pin head into the slot 4011. At this time, the ratchet piece 401 is connected to the limiting piece 402, and the swing frame 301 and the ratchet piece 401 are locked in one direction. Through the above process, the limiting piece 402 is switched to different slots 4011, thereby achieving the purpose of adjusting the size of the limiting angle between the two swing frames 301.

[0080] The connector 405 consists of a long rod and connecting rod joints located at both ends of the long rod. The two connecting rod joints are threadedly connected to the long rod. The orientation of the connecting rod joint interfaces is set as needed. The connector 405 is used to transmit power.

[0081] One end of the adjusting member 406 is connected to the connecting member 405, and the other end extends along the length of the second upright 103 to one side of the handrail 600, so that the user holding the handrail 600 can grasp the adjusting member 406 at any time, thereby avoiding the need to adjust the limiting angle between the two swing frames 301 by getting off the machine or bending over. The adjusting member 406 is used to help the user adjust the limiting angle between the two swing frames 301 during the standing leg-clamping training.

[0082] In some embodiments, the slot 4011 further includes a first slot and a second slot. The ratchet member 401 is provided with at least one first slot and a plurality of second slots. The first slot is located on any side of the plurality of consecutively arranged second slots. The first slot is used to cooperate with the limiting member 402 to lock the limiting angle in both directions. The plurality of consecutively arranged second slots are used to cooperate with the limiting member 402 to lock the limiting angle in one direction.

[0083] Specifically, the depth of the first slot is greater than the depth of the second slot. After the limiting member 402 enters the first slot, it is locked in both directions due to its deeper slot. The limiting member 402 cannot slide out of the first slot. The two-way locking can only be released after the pin head is pushed out of the slot 4011 by the top plate member 404.

[0084] After the limiting member 402 enters the second slot, it is locked in one direction. The limiting member 402 can slide out based on the shallow and inclined inner wall of the second slot. The limiting member 402 can change its position in multiple consecutively arranged second slots along a certain direction, thereby increasing the limiting angle. However, it cannot change its position in the opposite direction. The limiting angle can only be reduced after the pin head is pushed out of the second slot by the top plate member 404.

[0085] The first slot is located on either side of a plurality of consecutively arranged second slots. The first slot restricts the starting or ending position of the limiting member 402, preventing it from directly sliding and changing into the second slot. After the limiting member 402 is pushed out of the first slot and into the second slot by the top plate 404, the limiting member 402 is allowed to slide and change position in a plurality of consecutive second slots, thereby autonomously increasing the limiting angle between the two swing frames 301. However, it cannot change position in the reverse direction. The limiting angle can only be controlled to decrease after the pin head is pushed out of the second slot by the top plate 404.

[0086] It should be noted that the relative position locking of the two swing arms 301 includes one-way locking and two-way locking; during the adjustment of the limiting angle between the two swing arms 301, the two swing arms 301 rotate counterclockwise or clockwise relative to the ratchet component 401. One-way locking means that the swing arm 301 is absolutely locked in one direction relative to the ratchet component 401, while the corresponding other direction is not absolutely locked.

[0087] Two-way locking means that the swing frame 301 is absolutely locked relative to the ratchet component 401 in both the counterclockwise and clockwise directions.

[0088] Specifically, when the swing frame 301 rotates counterclockwise relative to the ratchet 401, the angle between the two swing frames 301 increases until the angle increases to a suitable angle (i.e., the limiting angle). By turning the pin head into the slot 4011, the ratchet 401 is connected to the swing frame 301. Based on the different inclinations of the inner walls on both sides of the slot 4011, the movement of the pin head is restricted only when it moves clockwise. That is, the ratchet 401 absolutely locks the swing frame 301 in the clockwise direction. This further restricts the movement of the swing frame 301 only when it moves clockwise. When the user wants to make the swing frame 301 swing clockwise relative to the first base frame 101, it is restricted by the ratchet 401, thus causing the ratchet 401 to move together.

[0089] Conversely, based on the different inclinations of the inner walls on both sides of the slot 4011, the movement of the pin head in the counterclockwise direction is not restricted. That is, the ratchet 401 does not absolutely lock the swing frame 301 in the counterclockwise direction. This further ensures that the ratchet 401 does not restrict the movement of the swing frame 301 in the clockwise direction. When the user wants to drive the swing frame 301 to swing counterclockwise relative to the first base frame 101, it is not restricted by the ratchet 401. Thus, the user can further increase the limiting angle without controlling the top plate 404 to push out the pin head.

[0090] Based on the above principle, if the swing arm 301 rotates clockwise relative to the ratchet 401, the angle between the two swing arms 301 increases, which is the opposite of the case. This will not be elaborated further here. The one-way locking allows the user to directly push the swing arm 301 before or during training to control the increase of the limit angle without being restricted by the ratchet 401. However, when it is necessary to control the decrease of the limit angle after training, it will be restricted by the ratchet 401. Therefore, it is necessary to push the pin head out of the slot 4011 through the top plate 404 before the limit angle can be controlled to decrease. Otherwise, the ratchet 401 will move together.

[0091] Reference Appendix Figure 1 and Figure 2 In some embodiments, the adjusting member 406 is rotatably mounted on the base frame assembly 100 at either end, and the end of the adjusting member 406 near the handrail 600 is used to pull the connecting member 405 to move relative to the first base frame 101.

[0092] Specifically, one end of the adjusting member 406 is connected to the connecting member 405, and the other end is used by the user to grip and adjust. The adjusting member 406 can be rotated to any position between its two ends on the second stand 103 so that the user can easily drive the connecting member 405 by adjusting the adjusting member 406.

[0093] Optionally, the rotatable connection between the adjusting member 406 and the second stand 103 is closer to the connecting member 405, so that the distance from the connecting member 405 to the rotatable connection is less than the distance from the user's grip to the rotatable connection. That is, the lever arm of the adjusting member 406 near the connecting member 405 is less than the lever arm near the user's grip, so that the user can move the connecting member 405 with a smaller force.

[0094] Reference Appendix Figure 4 In some embodiments, the top plate 404 or the ratchet 401 is provided with a limiting groove 4041, and correspondingly, the ratchet 401 or the top plate 404 is provided with a limiting post 4012. The limiting post 4012 extends into the limiting groove 4041, and the limiting groove 4041 and the limiting post 4012 cooperate to limit the relative movement range of the top plate 404 and the ratchet 401.

[0095] Specifically, when the connecting member 405 drives the top plate member 404 to move relative to the ratchet member 401, the edge of the top plate member 404 moves from the bottom wall of the slot 4011 towards the opening of the slot 4011, or the edge of the top plate member 404 moves from the opening of the slot 4011 towards the bottom wall of the slot 4011. Through the cooperation of the limiting post 4012 and the limiting groove 4041, the relative movement range of the top plate member 404 and the ratchet member 401 is limited, so as to prevent the top plate member 404 from pushing the limiting member 402 out of the slot 4011 too far, which would cause the elastic member 403 to be damaged and difficult to reset, or to prevent the top plate member 404 from having too large a stroke and being unresponsive.

[0096] Reference Appendix Figure 3 In some embodiments, the swing frame assembly 300 includes a swing frame 301, a foot pedal 302, and a leg pad 303, wherein the swing frame 301 is rotatably mounted on the first base frame 101, the foot pedal 302 is fixedly mounted on the swing frame 301, and the leg pad 303 is fixedly mounted on the swing frame 301 and located on one side of the foot pedal 302.

[0097] Specifically, the swing frame 301 is made of high-strength steel or other alloy materials to ensure its stability and load-bearing capacity during standing leg-clamping training, and to avoid deformation or damage after long-term use. One end of the swing frame 301 is rotatably mounted on the first base frame 101, and the other end is fixedly mounted on a foot pedal 302. When the user steps on the foot pedal 302, the swing frame 301 swings relative to the first base frame 101. The leg pad 303 is fixed on the swing frame 301 and located on one side of the foot pedal 302, and is used to assist the user in standing on the foot pedal 302 to apply force to the swing frame in a standing leg-clamping training with the buttocks unsupported.

[0098] In some embodiments, a synchronizing element is provided between the two swing frames 301, with both ends of the synchronizing element rotatably connected to the two swing frames 301 respectively. The synchronizing element is used to make the two swing frames 301 rotate synchronously relative to the base frame assembly 100.

[0099] Specifically, the synchronizing element consists of a short rod and connecting rod joints located at both ends of the short rod. The two connecting rod joints are threadedly connected to the short rod. The two ends of the synchronizing element are rotatably connected to two swing frames 301 respectively. The connection between the synchronizing element and the swing frame 301 rotates coaxially with respect to the foot pedal 302. The length of the synchronizing element is set based on the actual situation so that when the foot pedal 302 on one swing frame 301 rotates, it can push or pull the foot pedal 302 on the other swing frame 301 to rotate synchronously through the synchronizing element.

[0100] Reference Appendix Figures 1 to 4 When using the standing leg-clamping trainer of this application, preparation work is first performed, namely, adjusting the limiting angle between the two swing frames 301 during the exercise. The user first steps on the pedal 500 and holds the handrail 600, aligns both feet on the foot pedal 302, holds one hand and pulls the adjusting part 406 backward through the connecting part 405 to drive the top plate part 404. The edge of the top plate part 404 moves from the bottom wall of the slot 4011 towards the opening of the slot 4011, thereby causing the pin head located in the slot 4011 to resist the pressure of the elastic part 403 and be pushed out of the slot 4011. At this time, the connection between the ratchet part 401 and the limiting part 402 is disconnected, that is, the connection between the swing frame 301 and the transmission component 200 is disconnected. The user's legs adjust the limiting angle between the two swing frames 301 by driving the two foot pedals 302.

[0101] After the two swing arms 301 reach the maximum angle required for training, the user releases the adjustment piece 406. The adjustment piece 406 and the connecting piece 405 drive the top plate piece 404 to move in opposite directions. At the same time, the elastic piece 403 assists in pushing the pin head into the slot 4011. At this time, the ratchet piece 401 is connected to the limiting piece 402, that is, the swing frame assembly 300 is connected to the transmission assembly 200. At this time, the exercise preparation is completed, and the user can start the standing leg clamping training at the limit angle set by himself. During the standing leg clamping training, the user is in a half-squatting position so that the user applies force to the swing arm without supporting the buttocks to perform the leg clamping training, thereby avoiding the use of the waist or other parts of the body for leverage.

[0102] After training, the user pulls the adjusting piece 406 backward again at the maximum angle position. This pushes the limiting piece 402 out of the slot 4011 via the top plate 404. The user then pulls their legs inward, causing the swing frame 301 to swing towards the center to the minimum angle. At this point, the user releases the adjusting piece 406 and dismounts, ending the exercise. The coordination of the adjusting piece 406, connecting piece 405, and top plate 404 during this process is the same as in the exercise preparation stage and will not be repeated here.

[0103] This application provides a standing leg-clamping training device. It utilizes two swing arms 301, a handrail 600, and a footrest 302 mounted on the swing arms 301 to allow the user to perform leg-clamping training with unsupported hips. This improves training efficiency. An adjusting component 400 allows for quick adjustment of the limiting angle between the two swing arms 301, improving adjustment efficiency. The device uses a wheel and pin mechanism to bidirectionally limit the limiting angle, and a ratchet 401 and limiting member 402 to unidirectionally or bidirectionally limit the limiting angle. An elastic member 403 prevents the limiting member 402 from rotating out of the slot 4011, thus preventing the two swing arms 301 from rotating out of the slot. The relative position of 1 is unstable; the top plate 404, the connecting piece 405 and the adjusting piece 406 are used to quickly control the limiting piece 402 to change to another slot 4011; the limiting post 4012 and the limiting groove 4041 are used to limit the relative movement range of the top plate 404 and the ratchet 401; the transmission piece 201 and the lever piece 202 are used to change the direction of the force, so that the gravity of the resistance source is used to provide a counterforce for the relative swing of the user's legs in the horizontal direction; the first slot 4011 and the second slot 4011 and the limiting piece 402 are used to achieve flexible limitation of the limiting angle. Specific Implementation Example 2

[0105] This application also provides a standing leg-clamping training device, which differs from the first embodiment in that the first base frame, the first upright frame, and the second upright frame are replaced with a second base frame and a third upright frame. In this embodiment, the second upright frame is not provided, and the handrail is set on the second base frame. The first base frame and the second base frame have the same structure, the first upright frame and the third upright frame have the same structure, and the remaining components are the same as those in the first embodiment.

[0106] Specifically, the handrail further includes two support parts, two fixing parts, and two handle parts. The two support parts are fixedly mounted parallel to the second base frame and extend away from the second base frame. The lever 202 and the adjusting member 406 are rotatably mounted on the support parts at either end. The support parts are used to provide support for the lever 202 and the adjusting member 406.

[0107] Two fixed parts are fixed in parallel between the two support parts to keep the two support parts stable. Two handles are respectively located on the two support parts. The two handles are used for the user to grip with both hands. The two handles are used in conjunction with the foot pedal to support the user to stand and perform leg-clamping exercises. Specific Implementation Example 3

[0109] This application also provides a standing leg-clamping trainer, which differs from the first embodiment in that the handrail 600 is disposed on the side of the base frame assembly 100. Specifically, the handrail 600 is disposed on one side of the first base frame, and the other components are the same as those in the first embodiment. Specific Implementation Example 4

[0111] This application also provides a standing leg-clamping trainer, which differs from the first embodiment in that the adjusting component 406, connecting component 405 and top plate component 404 in the adjusting component 400 are replaced with the second handle component 700, and the remaining components are the same as in the first embodiment.

[0112] Reference Appendix Figure 6 In some embodiments, the adjustment assembly 400 includes two handles 700, one handle 700 being fixed to the swing frame 301 and the other handle 700 being fixed to the shaped plate. By clamping the two handles 700, the elastic member 403 is compressed, and the shaped plate causes the pin head to rotate out of the slot 4011, thereby disconnecting the ratchet member 401 from the swing frame 301, and thus the limiting angle between the two swing frames 301 can be freely adjusted. Specific Implementation Example 5

[0114] This application also provides a standing leg-clamping trainer, which differs from the first embodiment in that the adjustment component includes a wheel 800 and a pin, while the remaining components are the same as in the first embodiment.

[0115] Reference Appendix Figure 7 In some embodiments, the wheel component 800 is coaxially rotatably mounted on the first base frame 101 with any of the pendulum frames 301. The wheel component 800 is connected to the transmission assembly 200. The wheel component 800 is provided with multiple locking points. One end of the pin is provided on the pendulum frame 301, and the other end is used to insert or disengage from the locking point to adjust the limiting angle, thereby locking or releasing the relative position of the two pendulum frames 301 in both directions.

[0116] Specifically, the wheel component 800 is a circular, square or other shaped metal plate component. The wheel component 800 is coaxially rotatable on the first base frame 101 with any swing frame 301. The wheel component 800 is provided with a plurality of continuously arranged locking points, which are used to accommodate the pin component.

[0117] The swing frame 301 is also fixed with a pin seat 900. One end of the pin passes through the through hole of the pin seat 900 and extends into or out of the locking point to adjust the limiting angle. The other end of the pin is connected to a lifting member 1000. One end of the lifting member 1000 is rotatably mounted on the swing frame 301. The user drives the lifting member 1000 to rotate relative to the swing frame 301 through the other end of the lifting member 1000. The pin is located between the two ends of the lifting member 1000 to correspond to the through hole on the pin seat 900. The pin seat 900 is used to limit the relative rotation of the lifting member 1000, thereby limiting the depth of the pin inserted into the locking point.

[0118] The user moves the pin relative to the swing frame 301 by lifting the lifting component 1000, thereby inserting or disengaging the pin into the locking point and adjusting the limiting angle. Since the locking point encloses and restricts the pin, it provides bidirectional locking to the inserted pin, causing the swing frame 301 to rotate the wheel component 800. After the pin is disengaged from the locking point by lifting the lifting component 1000, the connection between the swing frame 301 and the wheel component 800 is disconnected. Specific Implementation Example Six

[0120] This application also provides a standing leg-clamping training device, which differs from the first embodiment in that two handrails 600 are disposed on the side of the base frame assembly 100 and on the base frame assembly 100. Specifically, one handrail 600 is disposed on one side of the first base frame, and the other handrail 600 is disposed on the first base frame. The remaining components are the same as those in the first embodiment.

[0121] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
